RHEXIA MARIANA. 
Class. Order. 
OCTANDRIA MONOGYNIA. 
This plant grows spontaneously in Mary- 
land and the warmer parts of North 
America: it has long been known in this 
country, but being somewhat tender, is 
easily lost in severe winters, on which ac- 
count it is rarely to be met with. 
It usually commences flowering in Au- 
gust, and continues throughout that month 
and the following, and may be esteemed a 
very ornamental herbaceous plant. e 
seeds scarcely ever ripen here, but are 
sometimes brought over from its native 
country. It also admits of propagation by 
the roots: these should be planted in pots 
of sandy peat earth, and preserved from in- 
tense frost, which will destroy them. If 
sheltered a little in summer, they will flower 
much larger and finer than if too much 
exposed.
